This chapter describes the features and operation of the embedded real-time analysis and diagnostic (ERAD) module. The ERAD module enhances the debug and system analysis capabilities of the device. The debug and system analysis enhancements provided by the ERAD module are implemented external to the CPU. The ERAD module consists of the enhanced bus comparator (EBC) units, the system event counter (SEC) units, and the cyclic redundancy check (CRC) units. The EBC units are used to generate hardware breakpoints, hardware watch points, and other output events. The SEC units are used to analyze and profile the system. The CRC units monitor CPU buses and compute the CRC when the self-test code is executed. This capability aids in achieving simpler, non-intrusive and interruptible self-test mechanisms with the Software Test Library (STL). The ERAD module is accessible both by the debugger and the application software, which significantly increases the debug capabilities of many real-time systems, especially in situations where the debugger is not connected.
